Welcome to Sound Deadening
Hi there! My name is Eduardo, I'm a car enthusiast from Portugal who loves silence. In this website you can check my sound deadening projects with pictures, videos, how-tos and some product reviews. Enjoy!
Current project: Opel Ampera
Boot and floor under the rear seats
The boot (or trunk) is the noisiest area in a car, especially in an hatchback like the Ampera. So I added Dynamat Extreme, Dodo Super Liner and Dodo Barrier MLV for a 1dB noise reduction.
|Idle||80 km/h||120 km/h|
|Factory||29 dB||59 dB||63 dB|
|Current||28.5 dB||57 dB||60 dB|
